Taeniopterygidae are a family of stone flies with about 110 described extant species. They are commonly called willowflies or winter stoneflies and have a holarctic distribution. Adults are usually smaller than 15 mm. [ 1 ]
Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great manoeuvrability in flight, and claws and pads on their feet enable them to cling to smooth surfaces.
They live in a lotic-erosional habitat. Larvae of giant stoneflies live in cool streams of small to medium size, in leaf and woody debris packs. They prefer swift riffles between cobbles and boulders.
